What are the world's deadliest natural poisons?

There are many surprises in nature, and not all of them are good. Among the bad ones we find, in particular, the strongest poisons in the world. While some species prefer physical weapons against their predators or competitors, others prefer more subtle means. Thus, these species produce highly toxic substances even in small doses. Poison can take different forms and act on different levels, but the result is often the same: death of the object exposed to it. So what are the strongest natural poisons in the world? Here's a brief overview of these unrelenting substances.
5. Amatoxins These toxic compounds are present in several species of poisonous mushrooms, including the Pale Grebe and the Stinky Fly. The latter two also produce the most deadly amatoxins in existence. It only takes 0.1 and 0.2 milligrams per kilogram, respectively, or about 7 milligrams for the average person, to kill an exposed specimen. How do these toxins work? Target and destroy liver and kidney cells. But what makes them so dangerous is that the symptoms only appear between 6 and 24 hours after ingestion.
4. Strychnine
This toxic substance is found in the chilibush, the fruit of Strychnos nux-vomica. About 2 milligrams per kilogram can be enough to make the poison deadly to the person who takes it. Strychnine blocks the chemical agents that control the nerve signals transmitted to the muscles, causing severe cramping, up to and including death. It causes fairly rapid death, as it takes only thirty minutes for strychnine to take effect.
3. Ricin
This deadly toxin is found in the seeds of the castor oil plant. Native to Central Africa, the latter has spread all over the world where the climate permits. The substance acts by attacking the RNA and blocking the synthesis of proteins in the cells, leading to their death. Thus, one molecule of ricin can destroy 1,500 ribosomes, the structures that synthesize proteins, per minute. Less than one milligram per kilogram can be enough to kill a person in a few days. 2. Cyanide Cyanides are one of the fastest poisons in the world. They can be produced not only by bacteria, algae, but also by plants. For example, they are present in the seeds of some fruits, apple seeds and almonds. Cyanide acts by binding to iron atoms in hemoglobin and an enzyme called cytochrome c-oxidase. Thus, it interferes with the use of oxygen, creating respiratory problems. A dose of 6 milligrams per kilogram is enough to cause death. Taking high doses of vitamin B12 helps remove cyanide from an infected body.
1. Botulinum toxin
Botulinum toxin is the deadliest natural poison in the world. It is produced by the bacterium Clostridium botulinum, which thrives in low-oxygen environments. The bacterial substance causes what is called botulism and acts by blocking the neurotransmitters that control muscle contraction, causing paralysis. Botulinum toxin is extremely dangerous because it only takes one millionth of a gram for it to become lethal. So a cup of tea containing about 500 grams of botulinum toxin could kill all of humanity.
And the rest... However, this list is not exhaustive, because the venom of certain animals, such as frogs or snakes, can certainly join the top of these poisons, which should be avoided at all costs.
